Bugatti Typ 50 1/4 Scale model
« on: February 02, 2017, 01:35:03 PM »
Hello,
like promised i start a build thread about my Bugatti Project.
It is based on the Pocher model of this Engine that i bought as Young man.
As far as i can remember i startetd with the planning in 2005 and made the first Chips in 2009.
The cas is made from Aluminium and all scratch build. No castings were used.
the only parts that were bought are the Rolerbearings, screws, Valvesprings an screws.

Hi guys,
here are some Pictures of the cam grinding machine. A friend of mine is also Building model engines and he lend me his machine.
You can see some blanks, some ready cams and some Details of the machine.
The template is from brass and is milled on a Rotary table.

Here is the oilpan/housing. Ist made of Aluminium plates that were soldered together. Iam a Little unhappy with the result because the soldering has a different colour then the alu.
If i would build it again i will weld the case together instead of soldering.
Two wterjackets are machined at this state. six to go.

What Nick said. Awesome.

I'd never heard of a cam grinding machine. Time for a little googling.

Wonderful pictures!

Great stuff. What was the solder you used to solder the engine block together?

Hi guys, thanks for the kind words.
I will post the pictures in chronoligical order. The engine itself is ready so far. Last two pieces that i have to build is the water pump and the blower. The blower will be a dummy. I am planning to fit the engine with a injection system like keith did.
The injector will be fittet in the blower housing.

At the moment i am working on the ignition system. Engine runs but not stable because of heavy noise in the rpm signal.
